If you did had a dollar for every reporter with an inside source who tells them how many Kindles have really sold, you’d at least be able to buy some Amazon stock. Now TechCrunch has decided their source isn’t playing them, and declares in a headline: “We know how many Kindles Amazon has sold…. 240,000 Kindles have been shipped since November, according to a source close to Amazon with direct knowledge of the numbers.” Not even a source at Amazon, but “close to Amazon.”TC
